The daughter said to her father, "Dad, there's something that my boyfriend said to me that I didn't understand." "What did he say?" the Dad asked. "He said that I have a beautiful chassis, lovely airbags and a fantastic bumper." Her Dad replied, "You tell your boyfriend that, if he opens your hood and tries to check your oil with his dipstick, I will tighten his nuts so hard that his headlights will pop out and he will start leaking out of his exhaust pipe."
